Abstract: A fluid container for supplying a consuming device with a working fluid, including at least one connector piece having a shut-off valve arranged therein for preventing undesired escaping of the working fluid from the fluid container. In order to increase safety against undesired emptying of the fluid container, it is provided that the valve closure body, in the closed state of the shut-off valve, is accommodated in the fluid container completely inside a contour formed by an outer edge of the connector piece, and provision is made, for support against the valve closure body, of a support, which, upon insertion of the connector piece into the receiving seat, engages at least regionally into the connecting duct and in this way displaces the valve closure body in the connecting duct.

Abstract: A housing for a hydraulic unit, in particular a master brake cylinder for a hydraulic motor vehicle brake system, has at least a first and a second separate formed elements which are arranged on at least one side of the housing for a spatially clearly defined mounting of the housing and introduction of clamping forces into an external holding device.

Abstract: An apparatus having a housing, a cavity which is disposed in the housing and which at least in regions is configured as a bore in which at least one piston and one piston spring associated with the piston are received, wherein the piston spring in the bore when activating the piston in the operation of the apparatus is compressed by the piston. The piston spring is configured from a magnetic or magnetizable material, the piston is configured from a non-magnetic material, and an assembly unit which comprises the piston having the piston spring is provided, and in which the piston spring is held on the piston by a magnetic field.

Abstract: A hydraulic unit for generating brake pressure for a hydraulic brake system, comprising a housing which is produced from a cast blank, wherein the cast blank has at least one receiving cavity which is provided for machining to form a receiving profile for sealingly receiving a connecting piece, which is connected to a fluid container and can be plugged into the receiving profile along a plug-in axis, wherein the housing comprises at least one piston bore for receiving at least one piston, which is driven along a piston bore axis into the cast blank.

Abstract: A hydraulic unit for producing brake pressure for a hydraulic motor-vehicle brake system, including a main body, a cavity arranged in the main body and having at least one first bore segment with a defined target diameter, in which a cylindrical piston moveable in the axial direction is arranged, which, in the cavity, bounds at least one pressure chamber filled with a hydraulic fluid, for producing brake pressure in a brake circuit, and at least a first and a second sealing element for sealing off the cylindrical piston, which sealing elements are arranged at an axial distance from each other. In order to provide a hydraulic unit that can be produced more effectively and economically while the technical requirements nevertheless remain fulfilled, the material of the main body in a surface layer of an inner wall of the cavity in the bore segment has a material microstructure that is work-hardened.

Abstract: The invention relates to a master cylinder, in particular for a controlled motor vehicle brake system, including a first and a second piston which is displaceable in a housing and has a captive spring, a first end of the spring bearing at least indirectly against the piston and a second end thereof against a sleeve which is displaceable with respect to the piston and the movement of which with respect to the piston is limited by a pin provided on the piston and by a stop washer, the stop washer being arranged on a free end of the pin. In order to avoid impact noise upon rapid release of the brake, the stop washer of the first piston has a device for the damped abutment of the sleeve.
